There was a question recently on the Py6S mailing list about what data sources are best to use to provide atmospheric parameters (such as AOT, water vapour and ozone) for use with 6S, other atmospheric Radiative Transfer Models (such as MODTRAN) or other atmospheric correction algorithms (such as ATCOR). In the spirit of ‘reply to […]

As part of my fellowship with the Software Sustainability Institute, I’ve written an article on Software Sustainability in Remote Sensing. This article was originally written a couple of years ago and it never quite got around to being published. However, I have recently updated it, and it’s now been posted on the SSI’s blog. I’ve […]

I was going to post this as one of my ‘previously unpublicised code’ posts, but that would be stretching the title a bit, as I have previously blogged about my implementation of the van Heuklon (1979) ozone model. This is just a brief update (in the spirit of my ‘previously unpublicised code’ posts) to say that […]

I’ve just had my second journal paper published, and so I thought I’d start a series on my blog where I explain some of the background behind my publications, explain the implications/applications that my work has, and also provide a brief layman’s summary for non-experts who may be interested in my work. Hopefully this will […]

The last few months have seen a flurry of activity in Py6S – probably caused by procrastinating from working on my PhD thesis! Anyway, I thought it was about time that I summarised the various updates and new features which have been released, and gave a few more details on how to use them. These […]

As a Fellow of the Software Sustainability Institute I’m always trying to make my software more sustainable – and one element of this is ensuring that my software works correctly. Although crashes might annoy users (which generally isn’t a good plan if you want your software to be well-used), a far worse problem is your […]

This is just a quick Public Service Announcement, to let you know that my two main pieces of software have got fancy new websites. Py6S (my Python interface to the 6S Radiative Transfer Model) and RTWTools (my set of extensions for ENVI) are now hosted at: www.py6s.rtwilson.com www.rtwtools.rtwilson.com For those of you interested in the […]

As part of my PhD I wanted to use a simple model which would give me an estimation of the atmospheric ozone amount given a location and time of year. A simple model to do this was created by van Heuklon in 1979, and was described in a delightfully simple paper (unfortunately not freely available […]

Another one of the things that came out of the Collaborations Workshop 2013 was the importance of licensing any software or code that you release. The whole point of releasing code is so that other people can use it – but no-one can use it properly unless you tell them what license you have released […]

I’m a big fan of Matt Might’s blog, and thought I’d implement one of his tips for blogging as an academic – namely Reply to Public. I’ve had a number of emails from Py6S users asking me questions about how to atmospherically-correct entire satellite images with Py6S – so I thought ‘d respond online, so that […]
